Complete Food Poisoning Lawsuit Guide

You ate at a restaurant, picked up takeout or opened something from the grocery store, and hours or days later you were sick: vomiting, diarrhea, cramps, maybe a fever. Or a recall named something you’d already eaten. If you’re worn out and wondering whether anyone is responsible, that’s normal.

Here’s the plain answer. You may be able to hold a restaurant, store, food maker or distributor responsible if the evidence shows that a specific food was contaminated and made you sick. Depending on the state, the claim can rest on negligence, strict liability or breach of warranty (Cornell Law School’s Legal Information Institute). In Michigan, a restaurant meal is a sale that carries the implied warranty of merchantability (MCL 440.2314(1)), and most injury lawsuits must be filed within 3 years (MCL 600.5805(2), (12)).

Health first: get care, and ask about a stool test. A lab result that names the germ can link your illness to a food and to other people who got sick (CDC). That link is usually the hard part: symptoms can start hours or weeks after eating, some of the same germs spread from person to person, and the business’s insurer will want proof that its food, not another meal, made you sick. Michigan’s rules are in the boxes marked “In Michigan.”

Is it food poisoning, and do you need a doctor?

The most common symptoms of food poisoning are diarrhea, stomach pain or cramps, nausea, vomiting and fever. Some germs make you sick within a few hours after you swallow them; others take days (CDC):

Not every stomach bug comes from food. You can get norovirus “from sick people and through contaminated food, water, or surfaces” (CDC).

When to see a doctor

CDC says to see a doctor if you have any severe symptoms, including:

• bloody diarrhea;
• diarrhea that lasts more than 3 days;
• a high fever, over 102°F;
• vomiting so often that you can’t keep liquids down;
• signs of dehydration, such as peeing very little, a dry mouth and throat, or feeling dizzy when you stand up.

Drink plenty of fluids if you have diarrhea or vomiting (CDC). Adults 65 and older, children under 5, people with weakened immune systems and pregnant women are at higher risk of severe illness. If you’re pregnant and have a fever and other flu-like symptoms, see your doctor: pregnant women are 10 times more likely to get a Listeria infection, and infection during pregnancy “usually leads to miscarriage, stillbirth, premature delivery, or life-threatening infection of the newborn” (CDC).

Infection with Shiga toxin-producing E. coli can trigger hemolytic uremic syndrome (HUS), which “can lead to kidney failure, permanent health problems, and even death.” HUS is a medical emergency. Its signs include little or no peeing, losing pink color in the cheeks and inside the lower eyelids, and unexplained bruising (CDC).

How common is food poisoning?

CDC’s most recent estimates, published in March 2025, are for 2019. Six major germs caused about 9.9 million foodborne illnesses acquired in the United States that year, and with a seventh, Toxoplasma gondii, they caused 53,300 hospitalizations and 931 deaths. Norovirus caused the most illnesses, about 5.5 million, and Salmonella the most deaths, about 238 (CDC; Emerging Infectious Diseases, April 2025). The figures cover only those seven germs and adjust for the fact that “only a fraction of illnesses is diagnosed and reported.” CDC says they can’t be meaningfully compared with its 2011 estimates.

What evidence shows which food made you sick?

To confirm the source of a multistate outbreak, health officials use three kinds of evidence: epidemiologic (who got sick and what they ate), traceback (following a suspected food back “through the points of distribution, processing, and production”) and food and environmental testing (CDC). One person’s claim can rest on the same kinds of proof.

A lab test that names the germ

Ask your healthcare provider whether you should be tested. They can test a sample of your stool or blood, and some results, without information that identifies you, are sent to PulseNet, “a database at CDC that looks for similar foodborne germs to identify outbreaks” (CDC).

Many providers now use rapid tests (CDC). Culture-independent tests detect a germ’s gene or antigen, but they don’t produce an isolate (the germ itself, grown from your sample), and isolates are needed for whole genome sequencing, whose results serve as the germ’s “DNA fingerprint.” CDC’s FoodNet program calls for clinical labs to culture samples after a positive culture-independent test, or to send culture-ready samples to public health laboratories (CDC FoodNet, 2024), so it’s fair to ask whether yours will be.

A report to the health department

Report your illness to your local health department. Prompt reports help health departments find outbreaks: they track reports and “look for groups of people who have similar illnesses and ate the same foods.” Officials may interview you about what you ate and did in the week before you got sick, and ask for receipts, your shopper card number or leftover food for testing (CDC).

A match to an outbreak or a recall

PulseNet is “a national laboratory network that uses DNA fingerprinting to identify bacteria making people sick and detect potential outbreaks,” with at least one laboratory in every state (CDC). Multistate outbreaks are usually identified by PulseNet, whose scientists look for groups of people sickened by bacteria with the same DNA fingerprint (CDC). A match to a strain that’s been traced to a food you ate can be strong evidence of the source. Check the lists yourself:

• Outbreaks: CDC’s current outbreak list posts notices from some of the multistate investigations CDC leads; not every outbreak CDC investigates gets one (CDC).
• Recalls: the FDA’s recalls page covers FDA-regulated products, though not all recalls are posted there (FDA). The U.S. Department of Agriculture’s Food Safety and Inspection Service regulates aspects of the safety of traditional (non-game) meats, poultry and certain egg products (FDA) and posts its own recalls. MDARD’s food recalls page links to both.

A recall helps, but you still have to connect the food you ate to your illness. For Listeria, CDC advises contacting a healthcare provider if you ate a recalled or outbreak-linked food and have a fever and other symptoms of listeriosis.

Receipts, card records, leftovers and packaging

“Original food packaging and labels can help investigators trace where food came from,” CDC says. Store or freeze leftover food with its original packaging or label, or at least write down the food and brand name, where and when you bought it, any “best by” or other dates, and product and lot codes (CDC). MDARD suggests a sealed plastic bag or container in the freezer. Keep grocery and restaurant receipts, card statements and delivery orders, and note your shopper card number.

A timeline of what you ate

“The food that made you sick is usually not the last food you ate,” CDC says. Write down everything you remember eating in the week before you got sick and the restaurants and events where you ate (CDC), along with when your symptoms started and who else got sick.

A made-up example: Dana eats a chicken wrap from a deli on Saturday and sushi on Monday, and she’s sick Monday night. The sushi seems like the obvious suspect. But her stool culture grows Salmonella, which can take 6 hours to 6 days to cause symptoms, and the health department finds three other people sickened by the same strain who ate at the deli. Her evidence points to the wrap.

Who can be held responsible for food poisoning?

“Contamination can occur at any point along the chain—during production, processing, distribution, or preparation,” CDC says; a sick food worker who doesn’t wash their hands carefully can spread germs, for example. So the responsible business can be the farm or processor, the distributor, or the restaurant, caterer or store that served or sold the food. Product liability can reach “any or all parties along the chain of manufacture,” from the maker to the wholesaler and the retail store (Cornell Law School’s Legal Information Institute). If the food was served at a hotel or resort, see when you can sue a hotel.

Who is named in a lawsuit should follow the evidence, such as the health department’s findings or an outbreak traceback.

Negligence, strict liability or warranty?

There’s no federal product liability law, so state law decides these claims (Cornell Law School’s Legal Information Institute):

• Negligence: did the business fail to use reasonable care, for example in storing, handling or cooking food? It “generally focuses on the defendant’s conduct” (Prentis v Yale Manufacturing Co, Michigan Supreme Court, 1984).
• Strict liability: was the product defective? Where it applies, a maker or seller can be liable “regardless of the defendant’s intent,” however careful it was (Cornell Law School’s Legal Information Institute).
• Breach of warranty comes from the sale and “generally focuses upon the fitness of the product, irrespective of the defendant’s conduct” (Prentis). A merchant’s goods must be fit for their ordinary purposes, and a statement of fact or promise about the food, such as a label saying lettuce was triple-washed, can create an express warranty (Michigan’s Uniform Commercial Code, MCL 440.2313, 440.2314).

Under any of these theories, you must show that something was wrong with the food and that it caused your illness. In the Michigan Supreme Court’s words, the plaintiff must prove “that something is wrong with it that makes it dangerous” (Prentis).

For meat and poultry from USDA-inspected plants, federal law can limit these claims: Michigan’s Court of Appeals held that claims against a meat processor, distributor and store over E. coli in ground beef sold in 1993, before the USDA treated that germ as an adulterant, were preempted by the Federal Meat Inspection Act (21 U.S.C. §§ 467e, 678; Boulahanis v Prevo’s Family Market, 1998).

What if an outbreak made many people sick?

An outbreak can strengthen your evidence, but your claim is still about your own illness and losses. It can take three forms (see how class actions and mass torts work):

• Your own claim or lawsuit, valued on your own illness.
• A class action, one lawsuit brought by representatives for a whole group. Under Rule 23(b)(3) of the Federal Rules of Civil Procedure, a court can certify a class only if shared questions “predominate” and a class action is “superior to other available methods.” Injuries make that hard: the rule’s drafters wrote that a “mass accident” injuring many people “is ordinarily not appropriate for a class action,” because questions of liability and damages would affect individuals in different ways (committee note to FRCP 23, 1966).
• A mass tort, separate lawsuits over the same outbreak. Federal lawsuits sharing “one or more common questions of fact” in different districts can be sent to one court for pretrial proceedings, in a multidistrict litigation, or MDL (28 U.S.C. § 1407(a)).

If you get a class action notice, check its deadlines: for a Rule 23(b)(3) class, it must say that the court will exclude any member who asks, and how and when to ask (FRCP 23(c)(2)(B)). If you were seriously ill, get advice before the opt-out deadline.

What can a food poisoning claim pay for?

There’s no reliable “average.” Value depends on how sick you were and for how long, the care and lost pay involved, any lasting harm, and how clearly the evidence ties your illness to the food. Damages generally fall into two groups (as Michigan defines them for product cases, MCL 600.2945(c), (f)):

• Economic damages: medical bills, lost wages and other losses with a price tag.
• Noneconomic damages: pain, suffering, mental anguish, emotional distress and other harm without a receipt.

See how pain and suffering is valued, and before you settle, who gets paid from your settlement and how injury lawyers get paid.

How long do you have to file?

Every state sets its own deadline, called a statute of limitations; see injury deadlines in every state. A warranty claim can also require prompt notice to the seller.

What to do next

1. Get medical care, and ask about a stool test. Tell each provider what you ate and where. Keep bills, pay stubs and a note of every day you missed from work.
2. Save the evidence: leftovers and packaging in the freezer, receipts, card statements, delivery orders and your shopper card number (how to preserve evidence).
3. Report your illness to your local health department, and check CDC’s outbreak list and the FDA and USDA recall lists. In Michigan, you can also contact MDARD about food you bought.
4. Write down what you ate in the week before, and tell the seller. In Michigan, notify the restaurant or store within a reasonable time, preferably in writing. Don’t give a recorded statement or sign a release before you’ve had advice (talking to an insurance adjuster).
5. Get a free case review. A lawyer can check whether the evidence points to a business, which theory fits and how much time is left. Ask whether they’ve handled foodborne illness or product cases, and get the fee agreement in writing. The decision to settle is yours, and in Michigan your lawyer must promptly tell you about every settlement offer (MRPC 1.2(a), 1.4(a)). Get a free case review, or, if you got sick in Michigan, compare Michigan injury lawyers.

What waiting can cost

• The evidence. Leftovers get thrown out, packaging gets recycled, and the details of what you ate in the week before you got sick, the period investigators ask about (CDC), fade.
• Warranty remedies. In Michigan, a buyer who doesn’t notify the seller within a reasonable time can be barred from any remedy for the breach (MCL 440.2607(3)(a)).
• Your right to sue. In Michigan, generally 3 years (MCL 600.5805(2), (12)); other states set their own deadlines.

What a good outcome looks like

You got the care you needed and you’re recovering. The lab result, the health department’s findings and your own records point to the food that made you sick, and the claim names whoever is responsible and is filed on time. Your medical bills and lost pay are covered by those responsible, along with compensation for what you went through, and you know what you’ll take home before you sign anything. From wondering whether one bad meal can be traced to anyone to knowing what made you sick, who answers for it and how long you have to act.
